-Walls, firelocks and glass-less airlocks now stop heat.

-Fire made more deadly, as the flames will add more damage and a fire can spread more quickly.
-Fire can break windows now, meaning they can potentially extinguish themselves by opening a window to space.
-Increased the delay for atmos to process a cell and airgroup, will help with the lag for 50 player servers.
-Minor tweaks were made.
--Plasma needing a bit more before displaying its overlay.
--Pressure can now damage you at 550 kPA. This was because it wasn't viable to set the pumps to over-pressurize a room and potentially kill people.
--High pressure warning shows at 325.
